l IHPRQVED SPRING SEA'ImBBD-BOTTOM.

-w', 1 maenauunumammmaummptmemmgpmnpemtrait, in the countyvof Wyne andState of Michigan, have invented s new and useful Improvement inSpringSeaLts; and I do declare thatlthe following is a. trne and accumtedescription thereof', reference being had. to the accompanying drawingsand to the letters of reference' makd'thereon and being a part of this4specification, in which- Figure 1l is aperspeotive of my improved andlFigune 2 is a eross-section on the line y y in g. 1.

`Similar letters ot reference indicate correspondingl pertain eachfigure.

Th'e nature ot' this invention relates to an improved construction ci'springs for Ahed-Imttomsn sofas, seats for miln'n'y carriages, and otherlike' purposes, and

consists in the peculiar and novel construction of the' springs, and -inthe method of securing the same to the senteframe, th whole lforming,when properly covered, adorable, highly'elastc, end economical seat.

In the drawings- -A represpnts a frame, preferably of wood, to which is'ecnred a series of transverse springs, B, iig. 2, each fwhich is formedfrom 'one piece of wire.

That portion of the spring which forms the breadth of the seat hascoiled in it series of helical springs, a.

'From the emi helices the ends .of the wire are turned doti-:mord andinward, and on n plane with the 'Mnl i l frnme each has another helixcoiled in it,'as. shown the arch is flattened from Vthe imposition ot a.weight,

thereon, it hns free hiteml play, subject only to the resistance of thehelices Vof," which eectunlly prevents it fronibeiug bent or set, asKwould be the vense were the helices a dispensed with und the'emls ofthe spring secured directly to the me. l Whnt'I claim as my invention,and desire to secure hy Letters Patent, is-' The continuous wire springB, having coiled in it the helices g. a', and provided with the porchesand hooks b, in connection with the frame A, substantially as described.
